T1 mapping is beneficial in many respects. However, as
with all other time-series acquisitions, motion is a
significant threat. Our sequence is specifically
designed to be robust to motion. GRAPPA calibration
scans are performed multiple times for artifact-free
image reconstruction and sub-voxel spin tracking is
applied to correct for motion-related spin history
distortions. The in vivo results show the promise of the
approach.
